• Do I have to compile the software?

• OTEQ users running Linux on personal computers or Solaris on Sun Workstations can use the pre-compiled executables that are available in the Download section of this Web site; compilation for these operating systems/hardware platforms is not required.

  Compilation is required in the following situations:

  • Executable files are not available for your specific operating system/hardware platform (Windows and Macintosh computers, for example).
  • Users need to modify the underlying computer code.
  • The dimensions of the analyzed problem exceed the maximum dimensions of the pre-compiled executables (see Section 5.5 of the documentation).

• When running OTEQ, I get "Error: Input File Not Found". What's wrong?

• This error occurs when OTEQ can not find the control, parameter, flow, or MINTEQ input file that it is looking for. All of these files must reside in the directory from which you are executing the OTEQ command. The control file must be named 'control.inp'; names for the remaining input files must correspond to the filenames specified in the control file.
